【摘要】 以金黄色葡萄球菌、枯草芽孢杆菌、大肠杆菌、铜绿假单胞菌、伤寒沙门氏菌、藤黄微球菌为供试菌,对刺松藻全藻甲醇/氯仿(1∶1)提取物各组分进行了初步的抑菌活性测试,结果表明石油醚组分C3具有一定的抗菌活性。对组分C3进行进一步的分离,从中获得一个纯化合物Ⅰ,通过波谱手段鉴定其结构为植醇乙酸酯。更多还原

【Abstract】 The bacteriostatic activity of the fractions of MeOH-CHCl3(1∶1) extract of the whole plants of Codium fragile were tested with Staphylococcus aureus,Bacillus subtilis,Eshericia coli,Pseudomonas aeruginosa,Typhoidal salmonellosis and Micrococcus luteus,Among them,crude fraction C3 isolated from petroleum ether-soluble of showed the bacteriostatic activity against Bacillus subtilis.The isolation of crude fraction C3 lead to a pure compound Ⅰ.On the basis of spectral data,it was characterized to be phytyl acetate.更多还原
